Intel is Little Endian - ARM can be either - how is the ARMv5 setup?  Big Endian or Little Endian?
What OS are you dealing with?  What compiler?
What happens if you move the double and int?  Could be padding issue in how the compilers for different ISA handle the alignment.  Is the Intel a 64bit CPU? (I know ARMv5 is not, that’s a “StrongArm” variant basically or Marvell. . .
Does the ARM compiler being used has proper library support for double?

Hi, Mark.

Compiler bug?  Maybe try turning off all optimizations?
